Review: A very high quality component that fits properly. - I installed the Dorman 917-561 rear transfer case housing on my 2001 Chevy Silverado 2500HD that has the 6.0L gas engine, 4L80E 4 speed auto transmission and the NP246 transfer case. It was a very high quality die cast aluminum with no casting flash and was machined cleanly. Dorman actually included color photos and instructions that were pertinent and important. I highly recommend also installing the Merchant Automotive 10001 transfer case pump upgrade. It is machined billet alum plate to bolt onto your oil pump and it will stop the oil pump from wearing pin holes in the rear of your case. The case fit perfectly and all bearings were already installed in the case! Do not buy the other brand cases that have bad reviews on the internet of not fitting back together properly (2 guys pounding it back together with hammers and blocks of wood). I removed the transmission cross member, rear cross member for the torsion bars and removed the t-case from the truck to change out the rear case. There is a large snap ring that fits in a groove in the rear output shaft area in the case, and a mating groove in the rear output shaft bearing. It is located under a rubber plug on top of the tail housing of the case. This snap ring has to be expanded in order to separate the two case halves. It would be difficult to access the snap ring from the top with the t-case still in the vehicle and nearly impossible to correctly reinstall it. Do yourself a huge favor and buy the 11" lock ring / snap ring pliers to expand this snap ring. A typical 8" lock ring plier used to expand lock rings on transmissions will possibly expand the snap ring enough to separate the case halves, but it does not have enough spread to expand the snap ring far enough to engage it in both groves to correctly install the 2 t-case halves. I had to use screw drivers (inserted through the 2 holes for the vehicle speed sensors) to get in front of the rear output shaft bearing and pry it up or rearward enough to engage the snap ring between the rear case and the rear bearing groove. A plastic tool is recommenced, but did not provide enough leverage in my situation. Review: 1999 GMC Sierra NP261 Transfer Case Perfect Rear Housing Replacement - Worked great to replace the rear housing on my 1999 gmc Sierra NP261 transfer case. The rear output shaft was super tight on the housing. I couldn’t get it on at first, so I had to take my old bearing and put it in and take it out a few times to almost polish/sand the area so I could mate up the rear housing to the front. It wasn’t going on otherwise. Just a little TLC and it worked perfectly. The oil fill/drain plugs are not the same size as the OEM plugs. That is my only complaint. It’ll just make it that much harder to find a replacement if I ever need one. A seized drain plug got me into this replacement in the first place. ## Features - Ideal replacement - this transfer case housing is a direct replacement for a cracked or leaking original equipment housing - Durable construction - this 100% new housing is precision-manufactured for reliable longevity - Century of experience - for over 100 years, Dorman Products has provided quality automotive replacement parts to its customers - Quality tested - this part has undergone try-on and material testing to ensure a quality fit and long service life - Ensure fit - Input your vehicle into the garage tool and check Confirmed Fit bar at the top of the page.

NP261HD transfer case... Worked perfect. *by S***T on June 11, 2022* I just bought this 2005 Silverado 2500HD with 160,000 miles. Noticed a leak on the transfer case. I was aware of the pump rub issue but was hoping for just a leaking rear output seal. I ordered this Dorman replacement half case kit just in case and pulled the transfer case anyway to inspect. Good thing I did! Looks like someone was in there already and had installed 2 upgraded anti rattle clips. 1 was broken and half of it was stuck to the pick up magnet. The other was in place but was too big for the arm of the pump plate it was stuck on. Regardless, the pump plate ate notches in 3 of the 4 saddles. The 5 o'clock positioned saddle was the worst and when I shined a flash light from the inside of the case, I could see the pin hole that was leaking. Couldn't see it from the outside. Lucky I caught it before things got worse. I also installed the "Merchant Auto" case saver kit on the pump rather than using the 4 steel clips that come with this Dorman kit. Didn't feel comfortable with them and I don't want to have to do this shitty repair again. The speed sensor hole and everything was machined perfectly to match up with the original front case and accessories. 1 major tip. Get yourself an 11inch retaining ring/ snap ring pliers. Will need it for the main shaft access slot on top to release the rear case and the pump retaining ring if you choose to swap out the plate.
